23.976 Encoding with TMPGenc plus.Jerky picture.Any suggestions

When I covert an AVI to MPEG the motion of the picture is jerky.The downloaded AVI is 23.976 fps when opened with Gspot.I want to convert to PAL (25 fps),so that I can burn it to DVD for my stand alone. I have converted to NSTC (29. fps),as my stand alone supports both PAL & NSTC,and used 3.2 pulldown with no effect.Is there any-thing else I can do?Do I have to convert to VCD (NSTC film),as this seems to be the only convertion that supports 23.976 fps, then try to burn onto DVD.I have read many threads and there does not seem to be an easy answer for a newbie like me.Is there no one out there who is a computer whizz??,and has an easy and FREE way to covert these files smoothly,after all is that not what the internet is all about?.

 

Hi, I had similar problems with the finished product blurring when the camera panned.

I used TMPGenc which has a tick box under the Other settings/quantize matrix for 'No motion search for still picture'. Try removing this and it should hopefully improve the finished product to a watchable standard.

I know how frustrating these things are as I've posted a problem with my dvd project.
Best of luck.

 

Thanks.I will give it a try

 

Thanks again Pingu10.I had done this before with some files,but without any success.This time it seems to work,and DVD product is a lot better,smoother,quality.There are some AVI downloads that seems as if you can only watch them on your P.C.,without getting any problems,which is a pain when you have shelled out a small fortune on a decent T.V..When will some-one give us a universal fps AVI that all T.V'S can use and DVD's can play.

 

Glad this seemed to work.

It also did the job with my first one but its true that it plays fine on the pc but it's only once you've burnt it that you see whether it's of a good quality.
I think I read somewhere that you can run it through a program like Power DVD to see how it will look although it still seems like the display on the pc will be fine?!

If only I can use TMPGenc to enable me to take the tick off, I'll be sorted too :-(
For some reason it keeps encoding blank video.

if u guys are still there..i have a similar problem. i am trying to convert kvcds (kvcd.net), but the motion in my output is jerky as well. There are basically minor little freezes throughout the entire movie, every couple of seconds. This is very annoying and i have tried everything i can to stop it. If u have any ideas please let me know thankyou

 

Sorry ruvard,I cant help.I have only worked with .avi's.
Hope there is some-one out there who can help.If you have not
done so already try and start a new thread for youre prob.
You may get a better response.
Good luck.

 

no, i convert avi to kvcd...the original format is avi

 

The jerky motion you are all talking about is frame rates. When you convert it from pal to ntsc you need to do a pull down conversion. Just converting 25fps to 29.97fps does not correct to difference it just drops frames which makes it appear jerky.

 

thanks...but i need to know what exactly a pull down conversion really is..and how to perform it using tmpgenc.

 

When you have opened youre file in TMPGEnc click next
there should be an other settings option,click this.
It should give you more options,click advanced.
On this window there is a 3.2 pulldown,click this.
It is to covert 24fps-30fps,(hopefully will do 23.976-29.976).
Then in quantize matrix,click No motion search.....
I hope that this gives you improved results.

 

Hey thanks...ur advice really worked. However, it created some other problems. Using 3.2 pulldown fixes the jerky motion, and makes the picture flow more smoothly, but it worsens the video qualtity. The video seems like it has thousands of black bars goin horizontally across the screen. This really makes the image distorted. If u have any other helpful advice please post it..thanks

 

Tmpgenc and Most other encoders Suck at Converting NTSC to Pal and Visa Versa and will cause Jumpy playback....

The only encoder i know of that produces Good Quality and does Good pal/NTSC conversions is "Canopus Procoder" which would be worth a Try...

a good other way to do a proper Pal to NTSC conversion is to use a frameserver Called "AVISynth" which you can use to Speed the 23.976fps Video and audio up to 25fps which works Perfectly But AVISynth is very difficult to Learn....

If your DVD player Supports Both pal and NTSC then you should just encode the NTSC file to NTSC useing 3:2 Pulldown , First set the "Encode Mode" to "3:2 Pulldown When Playback" and then set the "Frame rate" to "23.976fps(Internally 29.976fps)" and then encode and any Lines you see through the Video will only show up on your Monitor not on your TV set , this is because your Monitor can not display Interlaced Video properly were your TV set is Made to Display interlaced Video.....

 

thanks, thats a lot of help

 

Hello, I converted quite a few 23.976 movies that i downloaded. Hopes this helps. First i used the project wizzard in Tmpgenc, where it states content of video select (video movie). At the filter setting page (3/5)select other settings, at rate control mode drop down box select 2 pass VBR (VBR). Don`t worrie about the bit rate yet. Click ok, then next. Now at bitrate setting page you can ajust the bitrate. Try to fit as much of the movie on to the dvd as possible. Don`t go pass 4000 if you plan to add your own menu. you can click and drag the blue line on the graph at the bottom of the box. You can even drop the audio bitrate to get more of the movie on the dvd. I maybe wrong but the bigger you make the movie file the less of the jerky picture you`ll have. It works for me.

 

Nope still jjjjerky.Thanks for the suggestion anyway.

 

Interlaced Video will allways look Jerky on your PC Monitor because your PC Monitor can not Properly Display Interlaced Video but on your TV Set it should Look Perfect fine.....

do this with avisynth

to convert the framerate, basically there's 3 ways to do it.
first assumefps() which just speeds or slows down the frame. only works good for ntsc 24 to pal 25.

then theres changefps() it basically removes frames or adds.

convertfps() The filter attempts to convert the frame rate of clip to new_rate without dropping or inserting frames, providing a smooth conversion with results similar to those of standalone converter boxes. The output will have (almost) the same duration as clip, but the number of frames will change proportional to the ratio of target and source frame rates.

but it seems i only need to use dgpulldown for the player.

really tmpg has a 3:2 pulldown tag. follow minion's little guide

 

I converted NTSC(23.976)-NTSC(29.976),and this plays smoother
on my stand alone player.It also plays O.k on my moniter,which is
a flat plasma screen,dont know if that makes any difference.
My question is...Why does it use so much disc space.
When I converted the film it was in two halves.Using TMPGEnc I had
to make the mpg files as small as I could.When on Bitrate setting
page I moved slider to use 49% of disc for each file.When burning
I set preference to NTSC(Im using SONIC MyDvd).Get movies transfers
mpg to burner,it should be 98% of blank dvd disc usage(it is when
settings are on PAL)but it says that project is too big.
When I have coverted the .avi from TMPGEnc it says files are 920MB
and 1.04GB.This should add up to 1.96GB but for some reason it adds up to 3.42GB as I only have 1.25GB of free disc space left.The reason I ask is I did try before to encode to NTSC with avis that I
could only make as small as 1.02GB each and it just would not let me
fit them on 4.7GB disc.Is there a reason this happens.
Next I think I would like to try AVISynth.I downloaded the prog. and
am completely lost.How does this thing work?.How do you open,run,use it.When I do open and run it looks like there is more I should do.Do I have to associate it with notepad or media player.Is there a Dum-Dum guide out there for a newbie?.
